Or to elaborate on the above; the ST9400c fits onto a backplate that is almost identical to that which comes with a Hive, or a Wiser system (a Nest would require a little more rewiring) - which means a very simple task of replicating the existing wiring on to the new backplate. Then the existing...

Apologies if I've misunderstood, but do you mean terminals A and B on the boiler? These are a live and neutral supply to the Smartec receiver and shouldn't be connected across. See @4:30...

I've just been trying to think this through... Ignoring the OP's wiring centre mistakes; could the UFH wiring centre be powered up from the e-tecs configurable relay and the zone valve for C/H left open? At least then, you wouldn't be tempted to operate thermostats that appeared to be on, but...

It seems, I owe myself a small fortune!

With a multi tool, cut out a suitably sized section of the 3D panel, then fill the gap with a piece of standard 18mm MDF to provide a level surface for the fitting. Caulk any remaining gaps.

This thread is specifically related to connecting new thermostats/receivers to an ESI ESRTP6C wiring centre. Do you have this wiring centre? Have you attempted to replace the original ESI thermostat directly with a Single channel Hive? The above wiring centre provides a 5V supply to the ESI...

The two Brown wires in L of the EPH, would go to L on the Hive backplate. The two Blues in N to N. The two Green/Yellow wires must remain connected together - these can be parked in the earth terminal on the Hive. The Grey wire in terminal 2 (COM) on the EPH would go to terminal 1 on Hive. The...

Just for the sake of discussion, as twin & earth cable isn't considered to be double insulated; would 412.2.4 require mechanical protection from trunking to supplement the basic insulation? And is it now not an issue, with the sheathed earth T&E now available?

Yes.

The boiler power is simply daisy-chained through the EPH, from the fused connection unit. There is no reason why the Hive receiver can't be wired in exactly the same way. If you would like to show us the wiring behind the EPH, we may be able to guide you further.

Any space for a door at the bottom of the stairs?

Does it matter? As FMT has already highlighted, 'the regs' suggest that a landing, with a width and length greater than the minimum width of the flight, should be provided at the top and bottom of a flight. It makes sense that a door - either outward, or inward opening - would be on a landing...

If you don't mind a DIY approach, you could have a look at EMS Bus Gateway... https://bbqkees-electronics.nl/product/gateway-s3-standard-wifi-edition/ It's a project that allows home automation systems such as Home Assistant, or OpenHab, to interface with your boiler and monitor certain...

Thank you. I know and appreciate your experience - I really wasn't trying to have a go; just trying to understand the getting hurt comment, when we attempt to help many people with these type of electrical connections. It's almost worth the site having a disclaimer for DIY electrical work -...

May I ask what you mean here? Whilst we often warn against opening up a boiler, because it will disturb the room sealing, the... has the wiring terminals accessible without doing that. When the OP say... I believe they are simply referencing the yellow wire link that would have originally...

I would agree, given... However, the flex to the thermostat is a 4 core + earth. There looks to be plenty of slack in the cable at the thermostat end. If there is some at the boiler end, the cable can be stripped back at both sides - the blue wire can be connected to N on the boiler, and to...

Yes, a single phase induction motor (as typically used on these fans) wouldn't change its run direction, simply by swapping the wires around.

I think that would be unlikely, given... If this has recently started and you haven't noticed it before, it may be possible that there's a partial obstruction to the flow. If the exterior vent has shutters, have a look to make sure they open and close prooerly, when the fan is operating.

It depends on what building control measures were in place at the time of conversion. Currently, a loft conversion on a building over two storeys requires a protected route of escape to the outside - doors to habitable rooms on this route should be fire rated. Until recently, these also had to...

That may be the official line - even though the HC60NG was supplied with a few other stats, such as the CM67z etc. The main difference between the HC60NG and the BDR91 is bi-directional radio on the newer model - which isn't much of an issue with simple on/off control to the boiler, but it does...
